Abstract
The phase diagrams are studied of binary mixtures of compounds belonging to the following series: 4-cyanobiphenyl-4-yl-4n-alkylbiphenyl-4 carboxilates (nCBB) and isothiocyanotophenyl 4-(trans-4-n al-kylcyclohexyl) benzoates (nTPCHB). It is shown that the dimerization of the nCBB compounds decreases with the increasing polarity of the nTPCHB matrix. The kind and concentration of the nTPCHB matrix has an essential effect on the temperature range in which the reentrant nematic phase exists.Keywords
